Innovating for a Sustainable Future
Helping You Improve Your Energy Efficiency
Heliostorage is a privately held company based in Kokkola, Finland. Founded in 2019 after a series of product pilots initiated by a team of passionate young engineers in 2012, our company is dedicated to advancing efficient energy storage solutions. We are committed to contributing significantly to the Paris Agreement’s goal of net zero emissions by 2050, with our products aiming to help reduce emissions by one gigaton for our customers.
A brief history of our organization.
How It All Started
Heliostorage’s journey began with a group of creative engineers in a garage, determined to make heating better and more efficient. We were driven by the age old issue caused by seasonality; In winter, when it’s cold and sunny days are rare, buildings need heating. In summer, when there’s plenty of sun, buildings need cooling.
This led to a clever idea in 2015: What if you could save the summer’s heat, or winter’s cold, and use it when you actually needed it?
With that question in mind, we got to work. We experimented and tested with various configurations of solar thermal for heat capture, and borehole storage for saving the heat. Multiple iterations of the solution were tweaked and improved until we got it just right. By 2019, we had achieved a solution that was both technically and commercially viable and so Heliostorage was born.
The solution provides customers with consistent, reliable heating, without the need for fossil fuels, all while using less electricity than a heat-pump-only system. Not only does our solution provide emission reductions, but also cost reductions that will benefit customers for years to come.

Accelerating the Path to Net Zero
Sustainability in Focus
The urgent need to decarbonize and reduce emissions is driving global action, with Europe committed to achieving net zero by 2050. We believe energy storage will be a pivotal enabler of this transformation. Fossil fuels account for 71% of Europe’s energy demand, while renewables provide only 29%. Our goal is to accelerate the shift by decarbonizing electricity, enabling electric transportation, and reducing heating emissions for a cleaner future.
